Secondary caries driven by biofilm accumulation at restoration surfaces and tooth–restoration interfaces remains a major cause of failure for resin-based restorations, motivating the development of non-leaching, contact-active antibacterial dental resins. However, strengthening antibacterial/anti-adhesion performance by incorporating functional comonomers often compromises mechanical durability, largely due to reduced effective crosslink density and increased susceptibility to hydrolytic degradation. Here, we address this bioactivity–durability trade-off by synergistically incorporating a cellulose-derived methacrylated macromer/crosslinker (ECM) and a fluoride-containing quaternary ammonium methacrylate antibacterial monomer (DMAHDM-F) into a dental resin matrix. ECM serves as a multifunctional macromolecular crosslinking element to reinforce network integrity and enhance effective crosslink density, while DMAHDM-F provides covalently immobilized, non-leaching antibacterial activity via quaternary ammonium functionality. The optimized formulation (ACDR-5) combines high flexural strength and modulus with pronounced antibacterial efficacy against Streptococcus mutans . Moreover, ACDR-5 maintains > 90% viability of human gingival fibroblasts, indicating favorable cytocompatibility. This dual-functional, network-reinforced design provides a straightforward strategy to reconcile sustained antibacterial performance with mechanical durability in light-cured dental resins.

Outdoor facilities such as charging infrastructure and box-type transformers face simultaneous threats from icing in cold environments and fire hazards during service, creating a strong demand for multifunctional protective coatings. This study proposes a hierarchical coating design that synergistically combines a flame-retardant matrix with a photothermal superhydrophobic surface to achieve integrated anti-icing/de-icing and fire-safety functions. To realize this concept, dopamine-modified TiO₂ and flame-retardant modified cellulose were used to construct the coating matrix, while multi-walled carbon nanotubes and fumed silica were deposited on the surface to create a micro/nanostructured hydrophobic layer with enhanced light-to-heat conversion capability. This architecture enabled the composite coating to achieve a water contact angle of ∼147°, an icing delay time of 1902 s, and a maximum surface temperature of 71.8 °C under one-sun irradiation, demonstrating effective photothermal de-icing capability. Additionally, it exhibited ultrafast fire-alarm response (<3.5 s), stable alarm cycling behavior, and excellent flame retardancy, together with robust durability under extreme temperatures, water-flow erosion, and mechanical abrasion. Overall, this study demonstrates a cost-effective and scalable strategy for integrating flame retardancy, rapid fire warning, and efficient anti-/de-icing capabilities within a single coating system, offering considerable potential for protecting outdoor equipment in harsh environments.

The pervasive contamination of micro/nanoplastics (MNPs) has emerged as a growing threat to global ecosystems and human health. In this study, a sustainable remediation strategy was proposed using polydopamine (PDA)-modified bacterial cellulose (BC) nanofibrous spheroids (PDA-BC) for the efficient sequestration of MNPs from aqueous environments. The PDA-BC spheroids demonstrated robust capture performance over a wide particle-size range, as well as across varying temperatures, pH values, and salinities, achieving an adsorption capacity of 461.62 ± 61.43 mg/g for 100 nm polyethylene terephthalate (PET) MNPs. Effective removal was also demonstrated for multiple polymer types, including polystyrene (PS), polypropylene (PP), and polyethylene (PE), with maintained its efficacy in real-world water matrices. Mechanistic analyses revealed that the superior performance was attributed to the synergistic contributions of physical interception and interfacial interactions, including electrostatic interactions, hydrogen bonding, and van der Waals forces. Beyond remediation, the discarded MNPs-loaded PDA-BC adsorbents were upcycled into mechanically reinforced composite films via citric acid-mediated hot-pressing, resulting in a 42.06% increase in tensile strength. This work not only enabled effective MNPs sequestration but also transformed waste into value-added products, offering a closed-loop route solution for MNPs pollution mitigation.

Sustainable alternatives with enhanced performance have attracted a great deal of research attention in response to the growing environmental and energy problems posed by petroleum-based plastics. However, the mechanical strength, water resistance, and functional properties of conventional bioplastics are occasionally restricted, limiting their utility. In this work, we describe a versatile cellulose-based bioplastic created through combining citric acid as a cross-linker and Ketjen black as a conductive filler with a carboxymethyl cellulose matrix. The optimized composite exhibits outstanding mechanical properties, including a tensile strength of 51.31 MPa and an elongation at break of 50.24%, as well as considerable electrical conductivity of 76.15 S/m, and a notable electromagnetic interference shielding effectiveness of 22.71 dB at a thickness of 0.19 mm. Its environmental compatibility was validated through soil degradation tests, confirming 100% biodegradability within 100 days with no observed effects on plant development. This study offers significant potential for flexible electronics and sustainable packaging by providing an environmentally friendly and scalable technique for designing high-performance multifunctional bioplastics.

Structurally colored photonic pigments are widely used in decorating, paints, and security packaging due to their unique iridescent colors and nontoxicity. However, the poor solvent stability and single optical property of the photonic pigments hinder their applications in the fields of multilevel anticounterfeiting and information encryption. Herein, by integration of cellulose nanocrystals (CNCs) with fluorescent carbon dots, solid CNC films with both fluorescent and structural colors are successfully fabricated via a self-assembly strategy. Ultrasonic treatment is employed to modulate the structural color of CNC films across the visible spectrum. After that, CNC-based photonic pigments are produced by heat and pulverization treatment, displaying excellent solvent stability and good color responsiveness. Importantly, the CNC-based photonic pigments display structural color and fluorescence stability under a wide range of temperatures (−65–70 °C) and photoirradiation. In addition, polymers are used to encapsulate CNC-based chiral photonic pigments to produce photonic plastics and coatings with fluorescent and structural colors, which can be applied in multidimensional anticounterfeiting and photonic coatings. This strategy provides a pathway for the functionalization of biomass photonic pigments.

Active packaging with sustained release property of active compound and good absorption capacity towards exudates is highly desirable for extending shelf life of meat. Herein, a novel cellulose nanocrystal (CNC)-based antimicrobial foam was prepared by encapsulating cinnamaldehyde/ β -cyclodextrin inclusion complex (Cin/ β -CD-IC) for chilled meat preservation. CNC extracted from pomelo peel via acid hydrolysis (100–200 nm length, 25–30 nm width) was co-cross-linked with epichlorohydrin and Cin/ β -CD-IC complex to form a stable foam. The prepared foam exhibited uniformly porous structure, which was beneficial for enhancing water absorption capacity (1781.30%) and compressive strength (254.08 kPa under 80% strain). Antimicrobial performance demonstrated that released Cin inhibited the growth of Gram-negative and Gram-positive bacteria, with inhibition zones of 36.00–40.50 mm. Notably, the enhanced activity and improved sustained release of Cin were observed due to the formation of Cin/ β -CD-IC. The foam exhibited superior biodegradability and biocompatibility. Practical application showed that after 12 days, the pH, total volatile base nitrogen, and total viable count of chilled meat treated with the CNC/Cin/ β -CD-IC foam were 6.05, 15.40 mg/100 g, and 6.78 (log CFU/g), respectively, and lower levels of spoilage-related volatiles were confirmed by electronic nose analysis, indicating the potential application in chilled meat preservation.

Lateral flow test (LFT) has been a very popular platform for point-of-care testing (POCT). Traditionally, LFT uses (nitro)cellulose or microstructured polymer as the substrate. In this work, we develop a new LFT substrate by capillary deposition of cellulose on a microstructured polymer substrate off-stoichiometry thiol–ene (OSTE) synthetic paper, which is formed by interlocked slanted OSTE micropillars. This substrate has uniform thickness and stable lateral flow rate with customized design. The lateral flow rate can be adjusted by changing the dimensions of the LFT test strip, the concentration of deposited cellulose, or the Tween 20 concentration in cellulose to meet specific requirements. Spotting tests are conducted on this substrate to facilitate the following immobilization of immuno reagents. We successfully use this substrate in various applications including urine glucose detection (an enzyme-based immunoassay), iodate detection of saline solutions, and plasma separation from whole blood, which proves this substrate has enormous potential for LFT in POCT.

A novel one-step dissolution–acetylation process using [BMIM]Cl is developed for fabricating high-performance RC ultrafiltration membranes. • The optimized RC membrane exhibits a high pure water flux of 293.81 L·m −2 ·h −1 and excellent surface hydrophilicity of 17.79°. • The acetylation results in a denser, more uniform membrane matrix, enhancing both mechanical strength and selectivity. • This strategy has solved the performance and processing issues of the cellulose ultrafiltration membrane. Cellulose-based ultrafiltration (UF) membranes often suffer from limited solubility and poor processability, which hinder the precise control of membrane morphology and performance. Herein, a single-step dissolution-acetylation protocol employing the ionic liquid [BMIM]Cl is introduced to fabricate regenerated cellulose (RC) ultrafiltration membranes with tunable degrees of substitution and optimized microstructure. By systematically varying the acetylation time and acetic anhydride concentration, a series of membranes with substitution degrees from 12.4% to 30.3% were obtained. The RC 20-36 h membrane (30.3% substitution) demonstrated a pure water flux of 293.81 L·m −2 ·h −1 , bovine serum albumin (BSA) rejection of 83.44%, and flux recovery ratio of 89.59%. Surface hydrophilicity was enhanced (contact angle 17.79°), and tensile stress reached 1059 kPa owing to acetylation-induced disruption of intermolecular hydrogen bonding and increased chain rigidity. Uniform acetyl group distribution minimized structural defects and established a finely porous network that balances high permeability with selectivity and fouling resistance. This one-step approach integrates cellulose dissolution and functional modification in a single solvent, offering a sustainable and efficient route to high-performance UF membranes.

A bio-based thermoresponsive hydrogel (MCT) is constructed. • MCT demonstrates spraying advantage and environmental friendliness. • MCT exhibits excellent fire-extinguishing and fire-resisting performance. • MCT acts in both the gas and condensed phases during fire suppression. Large-scale forest fires have caused severe and irreversible environmental damage, making the rapid and effective prevention and control of forest fires an urgent global challenge. Currently, conventional water-based fire-extinguishing agents used for forest fire suppression exhibit poor adhesion, wetting ability, spreading performance, and environmental compatibility. In this study, a rapidly thermoresponsive bio-based hydrogel forest fire extinguishing agent (MCT) was successfully prepared by the hydration and intermolecular entanglement of cellulose derivatives and integration of trihydroxymethyl phosphorus oxide (THPO). At room temperature, MCT exhibits excellent fluidity and sprayability. When exposed to elevated temperatures, it undergoes a sol-gel phase transition, enabling strong adhesion to vegetation surfaces. MCT demonstrates good fire extinguishing performance and effectively suppresses heat and smoke release from natural pine wood (NW) during combustion. In the burning process, PO·and inert gases released from the decomposition of MCT suppress flame propagation in the gas phase, and the phosphoric acid compounds generated simultaneously promotes dehydration and charring in the condensed phase. Furthermore, MCT shows excellent biodegradability, storage stability (up to 30 days) and long-term fire-resistant effectiveness. This environmentally friendly and highly efficient bio-based thermoresponsive hydrogel provides a promising pathway for next-generation forest fire prevention and control technologies.

Sustainable crop protection relies on the development of pesticide formulations characterized by intelligent release performance and high biological safety. However, due to the reliance on costly functional additives and complex synthesis processes, achieving all these multiple functions simultaneously still poses a formidable challenge. Here, we report cost-effective methacrylic anhydride-functionalized cellulose nanocrystals (MCNCs)-stabilized high internal phase Pickering emulsion (IMI@MCNCs-HIPPE) as a template for constructing a smart insecticide system. Through in situ radical polymerization of N, N-Diethyl-2-propenamide (DEAAM), we synthesized IMI@MCNCs-g-DEAAM microcapsules that exhibit multi-stimuli responsiveness (dual-pH responsive and temperature responsive), efficient pesticide encapsulation (96.5%), and a high loading capacity (58.2%). The resultant microcapsules demonstrate sustained and controlled release along with exceptional spreading, adhesion, rainfastness, and photostability on corn and tomato leaves, outperforming the commercial EC (Bisair®). Bioassays against Rhopalosiphum maidis and Tomato leafminers confirmed superior insecticidal efficacy of the microcapsules, while safety assessments on seed germination, soil microbes, and zebrafish indicated excellent environmental compatibility. This research innovatively establishes a sustainable, cost-effective, and multifunctional nanocellulose-based platform, enabling controlled release, precise targeting, and improvement in biological safety, thereby providing critical technical support for sustainable agriculture.

Tunable compact lasers hold great promise as integrated light sources for sensing, display and lab-on-a-chip applications, yet most existing devices rely on complex manufacturing process or synthetic materials that conflict with environmental sustainability requirements. Here, we construct a green cholesteric liquid crystal host using plant-derived hydroxypropyl cellulose doped with an organic laser dye. The high viscous material has disordered helical structure with thermo-responsive property, enabling the switching between random laser and band-edge-enhanced random laser by regulating the photonic bandgap position relative to the gain band via temperature control. The coupling between the high-density band-edge state with the multiple scattering network results in tunable emission wavelength, lower lasing threshold, extended feedback path, multimode coexistence and circular polarization property. This work helps to elucidate the light-matter interaction in complex biobased photonic structures and showcases the possibility for sustainable optical devices.

The development of sustainable and economical active food packaging remains a critical challenge for enhancing food quality and safety. This study presents an innovative strategy by utilising rice bran, an abundant agricultural waste product, to synthesise rice bran–derived bacterial cellulose (RBC) as a high-value matrix for active food packaging. This matrix was reinforced with zeolitic imidazolate framework-8 (ZIF-8) to fabricate multifunctional nanocomposite films. Structural analyses confirmed the successful integration of ZIF-8 into the RBC matrix via hydrogen bonding without disrupting its inherent crystalline lattice. The incorporation of ZIF-8 significantly improved the physical and functional characteristics of the packaging. Specifically, the optimal formulation (0.2% ZIF-8) enhanced tensile strength to 42.72 MPa and improved barrier properties against water vapour and oxygen. Notably, the film loaded with 0.1% ZIF-8 exhibited remarkable antibacterial efficacy, achieving a 99.41% inhibition rate against Escherichia coli . During chilled pork preservation trials, the nanocomposite films effectively suppressed microbial proliferation, delayed lipid oxidation and minimised the accumulation of volatile spoilage compounds. These synergistic effects successfully extended the shelf life of the pork by 6 days, demonstrating the film's superior capacity to extend food shelf life and ensure microbiological safety. This work highlights the promising potential of valorising RBC as a sustainable and highly efficient platform for advanced active food packaging.
